Bearing vibration measuring apparatus, bearing vibration measuring method, and radial type bearing
First Claim
1. A bearing vibration measuring apparatus for detecting a vibration component generated from a bearing, which includes an inner ring, an outer ring, and a plurality of rolling elements arranged between the inner ring and the outer ring rotatable in a circumferential direction, in a state of pressing one of the inner ring and the outer ring while relatively rotating other of the inner ring and the outer ring to measure a vibration of the bearing, and detecting a defect of the bearing based on the vibration component, said apparatus comprising:
- a driving mechanism for pressing the one of the inner ring and the outer ring in an axial direction, wherein the driving mechanism is elongated and contracted for inclining the one of the inner ring and the outer ring.

Abstract
A bearing vibration measuring apparatus is an apparatus of measuring vibration of a bearing. The bearing vibration measuring apparatus detects a vibration component generated from the bearing in a state of pressing one of an inner ring and an outer ring of the bearing in an axial direction while relatively rotating other of the inner ring and the outer ring to detect a defect of the bearing based on the vibration component. The bearing vibration measuring apparatus includes a driving mechanism elongated and contracted for inclining the inner ring or the outer ring.

2. A bearing vibration measuring method for measuring vibration of a bearing including an inner ring, an outer ring, and a plurality of rolling elements arranged between the inner ring and the outer ring rotatable in a circumferential direction, said method comprising:
-
controlling to elongate and contract a driving mechanism capable of being elongated and contracted such that one of the inner ring and the outer ring is inclined in a state of pressing the one of the inner ring and the outer ring in an axial direction by the driving mechanism while relatively rotating other of the inner ring and the outer ring;
detecting a vibration component generated from the bearing; and
detecting a defect of the bearing based on the vibration component.
